On Saturday the 12th of November 2016 we are organising our annual global member meeting in the Netherlands. We welcome our foreign guests on Friday evening around 20 hours with drinks and snacks to get acquainted. The program on saturday contains various interesting lectures by (inter)national speakers. For the children there is entertainment in a special room next to the conference rooms. On Saturday evening we are organising a typical pancake dinner in an old farm for our foreign guests and volunteers

This year another European patient organisation will use conference rooms next to ours: the organisation for Lymphangiomatosis & Gorham’s disease (More information). The common medical issue is lymph problems. They are organising their own sessions and they participate in lunch and dinner.



On the 11th and 12th of November we offer the possibility for a medical diagnosis. You can choose between a simple (free) diagnosis or a comprehensive medical diagnosis. You can register (before 1 November) via the registration form for the Member meeting (bottom of this page).

Simple diagnosis

On Saturday the 12th of November we offer a free medical diagnosis in a separate room for privacy reasons. We advise to have an annual check in order to monitor the patient more closely.

Comprehensive diagnosis

On Friday the 11th of November we offer our members a comprehensive medical diagnosis in the Academic Hospital in Rotterdam. This diagnosis is not free of charge.
